IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 169,043, dated October19, 1875 application filed September 14, 1875.

To all whom it may concern:

Be it known that I, FREDERICK P.ROSBACK, of Springfield, in the countyof Greene and State ot' Missouri, have invented certain Improvements inGrain-Binder Attachment for Reapers, of which the following is aspecification:

The nature of this invention relates to the novelconstruction of agrain-binder attachment for reaper-s; and it consists in devices,hereinafter described, for continuously carrying a band of twine aroundthe bundle, and for tying a hard, solid knot therein, and throwing outthe bundle.

Figure l is a perspective view of my improved binder, showing it inposition to receive a bundle. The grain'is carried under the compressorAA by an apron. (Not shown in the drawing.) As the compressor closes, itputs the twine around the bundle; the separator B keeps the grain fromcrowding on the compressor; the twine is placed over the knot-tier O, asshown in Fig. 4:, and at the same time into D; the knot-tier then turnsaround once, making the loop, the nippers taking hold of the end of thetwine; the compressor then rises up, and the knife E cuts the bundlefrom the ball, the nippers D carrying the end of the twine back readyfor another bundle. The tightener F slips the knot off of the knot-tierto the bundle, making the knot perfectly tight, and pulls the end of thestring out of the nippers in the knot-tier O. The fork G, on thebackward movement of the compressor, passes out, throwing out thebundle.

Fig. 3 is the main driving-wheel. The slot operates on theconnecting-rod J, giving it a reciprocating motion, the slot being soconstructed as to give time for the tying of the knot, and the passingin of the grain. The slot K of Fig. 3 slides over the shaft of thewheel, in order to holdit firm, at the same time allowing an oscillatingmovement, given by the crank L, at'the other end. The nippers open andclose, in order to take the end of the twine. They'are operated by theeccentric slot in the end of the box at O. The pinion Z runs into thepinion Y of Fig. 4. The pinion U, with the flat side, goes on the shaftW, and connects to the driving-wheel T, it having a rack of cogs, X,equal to the number of cogs in pinion U, giving it one revolution toeach of that of T, and the flat side prevents it from turning fartheruntil the driving-wheel has made its revolution. The compressor A, whileit compresses the bundle, at the same time carries the twine around thebundle and carries the spool M. N is the slot that carries the twine. Ois the guide that carries the twine into the nippers D. P is the springthat operates the same. A is the back compressor. The nippers D are keptclosed by means of a sprin (Shown on drawing at P.) Q is the pinion thatoperates the compressors, B being a rack working compressor A, andoperates the pinion Q. The motive power to drive the binder is takenfrom the outside driving-wheel of the reaper, and attached to beveledpinion S, to which is at tached a common clutch to throw it in and outof gear, so that it is under full control of the driver.

The following is a description of the knot-tier O: The knot-tier issimply ash-aft bent at one end, with two slots in 'it-one for thenippers, and the other for the knot-tightener to operate in. The twineis placed over the knot-tier, so the end next to the bundle is at rightangles with the knot-tier, and the end next the spool is in line withthe nippers. When the knot-tier turns around it forms the loop, as shownin Fig. 4, and the nippers catch the end of the twine. Now the loop isready to be slipped up to the bundle, and to be out ofi from the spool,which is done first. The twine being cut, as before described, leavesthe ends of the twine in the nippers. Now the knot-tightener catches thetwine between the nippers and the loop, and slips the knot toward thebundle, preventing the bundle from expanding. The tightener then, whenthe knot is tight, pulls the end of the twine out of the nippers, turnsthe bundle loose, which is then thrown out by the fork G. v

The following is a description of the drivingwheel T: This is simply acog-wheel with a groove cutin one side, so constructed as to throw thecompressors down over the grain and hold them there until the knot istied in the twine. It then raises up the compressors, and holds them up,giving time for the grain to run in under .the coxnpressors on :theapron. The etlm tsideqfi h wh as a s n f wa equal" to that of the wheelU, Fig.5, in order to give one revolution to the knot-tier, and

then slides over the flat side of the wheel front of it is stopped, andall behind it passes on into the bundle. As the compressor rises, itstrikes the cam andraises the separator, as represented. i

{The following is adescription of the knottightenerF: Thispiecehasaslot-in it,s0 constructed nsttoallow the twine to pass into it,

but too narrow to allow the knot to pass through-it. Asit passes throughthe slot in the knot-tier, it takes the endof the twine between-the:loop andthenippers into the slot, and,.as the knotcannot pass throughit, slips it toward the bundle, thns preventinganyexpension ofthebundle; consequently the bundleremains as tight as it wasw hencompressed.

The following is ia description of the compr sens A A" 171m st?.eenstwetet e go on a frame, Figsjwhand 2, keyed toashaft, V, and areopera-ted by the crank. The compressor is attached to the frame, and isoperated by a pinion, Q. On the end are the nippers D,

that carry the end of the twine, which it receives from the .guide.O,.so%that it never loses the end of the twine. The hook in the endofthe .nippers is to prevent the twine from slipping out while the knot isbeing tied.

2. The knot-tying hook 0, provided with the slot, in combination withthe nippers D, as and for the purposedescribed- 3. Thearm A,.havingitightenerEanthknife E,.and thearm A having .nipners 12,131 0011- bination with the knot-tier. O substantiallyas described.
